Does anyone have any recommendations for a .NET c# wrapper for the (COM based) Task Scheduler 2.0 API ?

Couldnt find anything using Google.

(I am aware there are .net based schedulers such as Quartz.net, but I need the fully functioned GUI in the windows Scheduler)

Thanks,

Matt

    • Exactly what I was looking for. Task Scheduler is painful and the command line (schtasks) looks even worse. This API is working great so far. Thank you!

    • After successfully installing assemblies through Nugget it does not recognize TaskService in code. What can be the problem ?

    If you dont want to use any third party wrapper then below is the sample code to schedule task.Code works in Windows 7.

    //create task service instance ITaskService taskService = new TaskSchedulerClass(); taskService.Connect(); ITaskDefinition taskDefinition = taskService.NewTask(0); taskDefinition.Settings.Enabled = true; taskDefinition.Settings.Compatibility = _TASK_COMPATIBILITY.TASK_COMPATIBILITY_V2_1; //create trigger for task creation. ITriggerCollection _iTriggerCollection = taskDefinition.Triggers; ITrigger _trigger = _iTriggerCollection.Create(_TASK_TRIGGER_TYPE2.TASK_TRIGGER_TIME); _trigger.StartBoundary = DateTime.Now.AddSeconds(15).ToString("yyyy'-'MM'-'dd'T'HH':'mm':'ss"); _trigger.EndBoundary = DateTime.Now.AddMinutes(1).ToString("yyyy'-'MM'-'dd'T'HH':'mm':'ss"); _trigger.Enabled = true; ///get actions. IActionCollection actions = taskDefinition.Actions; _TASK_ACTION_TYPE actionType = _TASK_ACTION_TYPE.TASK_ACTION_EXEC; //create new action IAction action = actions.Create(actionType); IExecAction execAction = action as IExecAction; execAction.Path = @"C:\Windows\System32\notepad.exe"; ITaskFolder rootFolder = taskService.GetFolder(@"\"); //register task. rootFolder.RegisterTaskDefinition("test", taskDefinition, 6, null, null, _TASK_LOGON_TYPE.TASK_LOGON_NONE, null);

      From where did you get the ITaskService, TaskSchedulerClass, ITaskDefinition, ITriggerCollection, ITrigger, IActionCollection, IAction, IExecAction, and ITaskFolder? The assembly with those classes and interfaces is not readily visible in Visual Studio 2010.

      Nevermind - I found the "taskschd.dll" file and after letting Visual Studio generate an Interop wrapped, was able to import it into my project. If only I could do the same with the PowerShell ISE and have it deploy to the destination target machines...

    Is the command line good enough?

    You can get fully functioned GUI through following Nuget command.

    PM> Install-Package TaskSchedulerEditor
